Abstract
Planar waveguides of the allyl polymer poly-(terephthal acid diallyl ester) (PDATP) exhibiting a particular high stress optical coefficient are investigated. Internal mechanical stress may be introduced in the wave-guides by the in-diffusion of small vapour molecules or by the activation of a piezoelectric transducer in the substrate. Based on the induced stress the feasibility of gas sensors or electro acousto optic phase shifters (V π=180 V) with these waveguides is discussed.
